Keep in mind, you've made a mistake. It's clearly stated for "The Division" and nowhere does it claims to work for "The Division 2"
Even videos of "The Division", so this is completely an oversight on your end.

Even tho as @Yang stated above we don't do refunds since the product was used, I am making an exception here.
You've been refunded, it should appear on your card in 5 to 10 business days.

Please, next time pay more attention when you purchase something online.
